miskamm [114]

Answer:

Step-by-step explanation:

Given

7x + 2 = 16

Subtracting 2 from both sides

7x + 2 - 2 = 16 - 2

7x = 14

Dividing both sides by 7

7x / 7 = 14 /7

x = 2

Hope it will help :)

Radius OA of circle O has a slope of 2.5. What is the slope of the line tangent to circle O to point A?

mixer [17]

The tangent at A is perpendicular to OA, so has a slope that is the negative reciprocal of that of the radius: -1/2.5 = -2/5.

A lab technician is dividing a cell that has a diameter of 4.32×10^-4 millimeters. Each of the new cells has a diameter measurin

RideAnS [48]

Answer:

$2.16 \times {10}^{ - 4}$

Step-by-step explanation:

The lab technician is dividing a cell that has a diameter of

$4 .32 \times {10}^{ - 4}$

The new cells has a diameter that is half of the diameter of the original cell.

The diameter of the new cell is given as:

$\frac{4.32 \times {10}^{ - 4} }{2}$

Rewrite the numerator in standard notation:

$\frac{0.000432}{2}$

$= 0.00216$

We rewrite in scientific notation to obtain:

$2.16 \times {10}^{ - 4}$
